Arguments:

NULL, or a pointer to a location where the function
can store the value passed to
pthread_exit()
by the target thread.

abstime

A pointer to a
timespec
structure that specifies the maximum time to wait for the join,
expressed as an absolute time.

Library:

libc

Description:

The pthread_timedjoin() and
pthread_timedjoin_monotonic() functions are QNX Neutrino
functions that are similar to the POSIX
pthread_join()
function, except that they give an error of ETIMEDOUT
if the join
doesn't occur before the absolute time specified by abstime passes
(i.e. the system time is greater than or equal to abstime):

If you are not too long, I will wait here for you all my life.

— Oscar Wilde, The Importance of Being Earnest

The pthread_timedjoin_monotonic() function uses
CLOCK_MONOTONIC, so the timeout isn't affected by changes
to the system time.

The pthread_timedjoin() and
pthread_timedjoin_monotonic() functions block the calling thread
until the target thread thread terminates, unless
thread has already terminated. If value_ptr is
non-NULL and the functions return
successfully, then the value passed to pthread_exit() by
the target thread is placed in value_ptr. If the target
thread has been canceled, then value_ptr is set to
PTHREAD_CANCELED.

The target thread must be joinable. Multiple
pthread_join(), pthread_timedjoin(),
pthread_timedjoin_monotonic(),
ThreadJoin(), and ThreadJoin_r() calls on the
same target thread aren't
allowed. When pthread_timedjoin() or
pthread_timedjoin_monotonic() returns successfully, the
target thread has been terminated.

Returns:

EOK

Success.

EBUSY

The thread thread is already being joined.

EDEADLK

The thread thread is the calling thread.

EFAULT

A fault occurred trying to access the buffers provided.

EINVAL

The thread thread isn't joinable.

ESRCH

The thread thread doesn't exist.

ETIMEDOUT

The absolute time specified in abstime passed before the
join occurred.
